TO ALL WHOM IT MAYCONCERN:

Be it known that I, THOMAS HAIGH, of Harrisburg, in the county ofDauphin, and State of Pennsylvania, have invented a new and usefulImprovement in Churns; and I do hereby declare that the following is afull,

clear, and exact description thereof, which will enable others skilledin the art to make and use the same, ref-- erence being had to theaccompanying drawings, forming part of this specification, in whichFigure 1 represents a front elevation of my improved churn, and having aportion of the box broken away, to exhibit the dasher within.

Figure 2 is a detail sectional view of one of the trunnions, enlarged,also showing part of the gearing, dasher-shaft, frame, and box.

This invention consists in a cubical or oblong box, by means of suitabletrunnions afiixed to any two diagonally opposite corners of the saidbox, and providingthe box with an internal dasher or revolving frame,which is actuated by suitable mechanism to revolve in a contrarydirection to the box, and thus produce a thorough agitation of the milk,whereby butter will be formed in a short time.

In the accompanying drawings, A is the box, and b d the trunnions at thediagonal corners, the said trunnions having bearings in the frame-postsB B.

C is the dasher-frame on the shaft-rod e. One end of this rod has abearing in the trunnion d, and, passing through the said trunnion, isprovided with a. grooved wheel, D.

This trunnion also bears a cog-wheel, E, which engages with a smallercog-wheel, G, the shaft of which latter bears a grooved pulley, H,which, in connection with a belt, f, transmits motion to the wheel D,and through it to the dasher C.

The trunnion bis provided with a crank-handle, 9. By turning the crank,the box A and the dasher G are revolved in opposite directions, and fromthe proper difi'erence in the diameters of the several wheels in theoperative mechanism, the dasher is revolved at the proper efiectivevelocity, which, together with violent surging and fluctuation of thecream, occasioned by rapidly-changing inclinations of the sides of thebox, conduces to, the production of the butter in a comparatively shorttime.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent 1. Suspending the cubical box between the posts B B,by attaching the trunnions b d to two. of its diagonally oppositecorners, whereby, as the box is rotated, the inclinations of its sidesare rapidly changed, as herein shown and described.

2. The cog-wheels E G, and pulleys D H, and hollow trunnion cl, alloperating together, substantially as described, in combination with thediagonally-suspen'ded box and its dasher, all substantially as shown anddescribed, and for the purpose set forth. i

The above specificationof my invention signed by me, this fifth day ofJune, 1868.
